b'VitroEase negative stainsThermo Scientific VitroEase Methylamine Tungstate and Thermo Scientific VitroEase Methylamine Vanadate Negative Stains are easy, ready-to-use negative stains for electron microscopy (EM) analysis.Highlights:Provided as a stable, ready-to-use 2% stain solutionEasy to use with straightforward staining protocolUniform, electron-dense stain for EMDries without crystallization, ideal for EM gridsVitroEase Methylamine Tungstate Negative Stain is a ready-to-use stain with excellent spreading qualities with high density for good contrast. It wets both grid films and specimens well at neutral pH. This stain does not damage delicate structures as much as phosphotungstate (PTA) and has been found to be useful for negative staining of macromolecules, viruses, and membranes.VitroEase Methylamine Vanadate Negative Stain is a ready-to-use stain with excellent spreading properties at a near-neutral pH of 8. It produces a light, uniform negative stain for high-resolution fine structure visualization and does not denature proteinFigure 4. TEM images of negative-stained apoferritin using the samples. This stain is also stable and nonvolatile in the electronVitroEase Methylamine Tungstate and VitroEase Methylamine beam, making it more resistant than uranyl acetate negative stain.
